The aim of this research is to find out the significant difference between successful seller and unsuccessful seller on self-efficacy and persuasion capability. Self-efficacy is people’ judgement about their capabilities to deal a problem at specific situation. Persuasion is a process communication that purposed for changing someone’s belief and behavior. The participants of research consists of 125 sellers, in which 80 are successful and 45 are unsuccessful. The data were taken by questionnaires. The processing technique is using t-test with SPSS (...) program 12.00 for Windows. The result of this research shows t(125) = -6.011, p<0,05, based on significant number 0,00. This shows the significant difference between successful seller and unsuccessful seller on self-efficacy. Furthermore, the number shows the level of self-efficacy on successful seller is higher compared to the level of self-efficacy on unsuccessful seller. On the other hand, the results of persuasion research shows t (125) = -7.501, p<0,05, based on significant number 0,00. This shows the significant difference between successful seller and unsuccessful seller on persuasion. The number also shows the level of persuasion on successful seller is higher compared to the level of persuasion on unsuccessful seller. (shrink)

The release of over 6,000 genetically modified mosquitoes (GMM) into uninhabited Malaysian forests in 2010 was a frantic step on the part of the Malaysian government to combat the spread of dengue fever. The field trial was designed to control and reduce the dengue vector by producing offspring that die in the early developmental stage, thus decreasing the local Aedes aegypti population below the dengue transmission threshold. However, the GMM trials were discontinued in Malaysia despite being technologically feasible. The lack (...) of systematic studies in terms of cost-benefit analysis, questionable research efficacy and safety-related concerns might have contributed to the termination of the field trial. Hence, this research aims to evaluate the feasibility of GMM release in Malaysia by using a holistic approach based on an Islamic ethical-legal assessment under the maslahah-mafsadah (benefit-risk) concept. Three main strategies based on the maslahah-mafsadah concept approach have been applied: 1) an evidence-based approach, 2) an impact-based approach and, 3) a priority approach. The analysis concluded that GMM could be categorised as zanniyyah (probable). GMM is a promising alternative for dengue control, but many issues must be addressed before its widespread adoption.

The occurrence of a new strain of SARS-CoV-2 cannot be ruled out. Therefore, this study seeks to investigate the possible effects of a hypothetical imperfect anti-COVID-19 vaccine on the control of not only the first variant of SARS-CoV-2 but also the second variant of SARS-CoV-2. We further examine the rates and a, escape of quarantined infectious individuals from isolation centers. The control R c and basic reproduction numbers R 0 are computed which gives assess to obtain asymptotic stability of disease-free (...) equilibrium point globally and the existence of a unique persistent equilibrium solution. Numerical results reveal that people infected with the second strain who are vaccinated with an imperfect vaccine are under control but the prevalence of the second variant enhances the prevalence of the first variant. Thus, discovering a vaccine that is effective for the prevention of variant 2 is necessary for the control of COVID-19. Numerical results also reveal that increase in the rate at which individuals infected with the first variant escape the isolation center gives rise to the population infected with the first variant and lowers the peak of the population infected with the second variant. This is probably because individuals infected with the second variant appear to be more careful with their lives and get vaccinated more than individuals infected with the first variant. (shrink)
